  • Best Practices for Dow Dowsil 786 Silicone Sealant

    *See Terms of Use Below

    1. Application

      DOWSIL™ 786 Silicone Sealant can be applied directly from the caulking cartridge with either an air-operated or hand-operated cartridge gun. Do not break the cartridge seal until just before use.

      After applying the sealant and a skin has formed, do not disturb the joint for 48 hours. A previously opened cartridge may be reused by removing the cured plug of sealant from the tip.

    2. Clean-Up

      Excess sealant should be cleaned off tools and surfaces while it is in the uncured state, but using a commercial solvent such as isopropyl alcohol or mineral spirits.
